@Nikki RobinsonDenver is great city & real estate market - irrespective of marijuana legalization.However, that issue has also provided an economic boost.I was watching Bloomberg TV a couple of weeks ago & they decided to interview the founder of Marley Coffee. 

Once we do about a 100k rehab It will produce us an 8.5 cap at 2$/sf NNN if we just lease to regular medical and/or related businesses as it's right in the middle of a very heavily populated medical zone.Depending on timing and wether Marijuana gets a green light in November in 26 States including Cali we could lease it to a MJ dispensary on a 20 year lease with a  high double digit cap NNN.Personally, I think the train has left the station on MJ and the Fed will have no choice but to acquiesce to the desires of the 30 plus stated that will have legalized or at least de criminalized it.

@David Cruice It is just violations for weeds (not marijuana) growing and refusing to remove.

Late rent and utilities, smokes a lot of marijuana in his room, loud when we're sleeping, and the list goes on.  

I'm not a lawyer, no legal advice, but I think that is proper for me as I would consider acceptance if it was, like, caught with marijuana several years ago and nothing since then.  

One tenant used & offered to me; Said he had medical use marijuana.

A lot of this information bounces around in my head, so I find it somewhat therapeutic to write it down in a public forum.

I have a duplex that I have a very strong premonition that they are smoking marijuana in the house.

It was almost therapeutic for them to get it off of their chest to someone that they felt was going to do something bigger with it. 

I have two children with special needs and when my wife and I used to rent, even though no pets were not allowed, they would allow us to have a therapeutic pet for my sons.
